Thanks aaron , your patch is working on my kernel. But the values are strange : vt1211-isa-6000 Adapter: ISA adapter Algorithm: ISA algorithm in0: +1.87 V (min = +0.00 V, max = +2.55 V) in1: +1.95 V (min = +0.00 V, max = +2.55 V) in2: +1.15 V (min = +0.00 V, max = +2.55 V) in3: +1.89 V (min = +0.00 V, max = +2.55 V) in4: +2.03 V (min = +0.00 V, max = +2.55 V) ERROR: Can't get IN5 data! fan1: 4519 RPM (min = 0 RPM, div = 2) fan2: 0 RPM (min = 0 RPM, div = 2) temp2: +187.0 C (high = +255 C, hyst = +0 C) ! really high for Celsius temp3: +107.2 C (high = +255 C, hyst = +0 C) ERROR: Can't get TEMP4 data!
